In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure marks in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0025] The present invention provides a vertical indoor unit, referring to Figure 1 and Figure 2 As shown in the figure, the vertical indoor unit includes a shell 1 and a heat exchanger 2, a fan 3 and an induced air duct 4 arranged in the shell 1, and the shell 1 is provided with a first air inlet 11, a second air inlet 12 and a first air outlet 13; the heat exchanger 2 is arranged at the first air inlet 11; the fan 3 has a volute 31, the volute 31 is connected to the downstream of the heat exchanger 2, and has a second air outlet 311a, the opening of the second air outlet 311a can be set upward, the second air outlet 311a is connected to the first air outlet 13, and the second air inlet 12 and the volute 31 are connected through the induced air duct 4.

[0026] Through the above technical solution, when the vertical indoor unit of the present invention is in use, the wind introduced into the volute 31 includes two parts, one part comes from the first air inlet 11, and the other part comes from the second air inlet 12, wherein the wind from the first air inlet 11 first passes through the heat exchanger 2 for heat exchange, and then flows into the volute 31, while the wind from the second air inlet 12 is introduced into the volute 31 through the air duct 4 under the negative pressure inside the volute 31, that is, the wind from the second air inlet 12 does not pass through the heat exchanger 2 and flows into the volute 31, and then The wind from the second air inlet 12 and the wind from the first air inlet 11 are mixed under the action of the fan 3 and blown into the room through the first air outlet 13. In this way, since the wind from the second air inlet 12 does not pass through the heat exchanger 2, the wind from the second air inlet 12 can be used to avoid the temperature of the wind flowing out through the first air outlet 13 being too low or too high compared to the set temperature. As a result, the temperature of the air blown out by the vertical indoor unit of the present invention is more comfortable and pleasant, thereby improving the user experience and comfort during use.

[0027] In the vertical indoor unit provided by the present invention, driven by the impeller of the fan 3, the wind in the volute 31 has a relatively high wind speed, and the second air inlet 12 is directly connected to the volute 31 through the induced air duct 4, so that a large negative pressure is formed at the connection point between the inside of the volute 31 and the induced air duct 4. Under the action of this negative pressure, the natural wind in the room will be introduced into the volute 31 through the second air inlet 12.

[0028] In the exemplary embodiments provided in the present disclosure, referring to Figure 1 and Figure 4 As shown in , the central axis c of the volute 31 can be set to extend laterally, and the volute 31 has a main body 312 and an air outlet section 311. The main body 312 is used to form a spiral wind, and the air outlet section 311 is located outside the main body 312 and the wind inside has a higher wind speed. The air outlet section 311 has a width in the longitudinal direction, wherein the width of the air outlet section 311 gradually increases from bottom to top, and the air induced duct 4 is connected with the air outlet section 311. Through such a setting, the second air inlet 12 can be connected with the air outlet section 311 with a higher wind speed through the air induced duct 4. In this way, when the indoor natural wind is introduced through the second air inlet 12, not only will the contour of the main body 312 of the volute 31 not be destroyed, but it can also ensure that a large negative pressure can be formed at the connection between the volute 31 and the air induced duct 4, so as to facilitate the smooth introduction of indoor natural wind.

[0029] In order to further reduce the influence of the setting of the communication port 311b on the profile of the volute 31, the communication port 311b may be set at a position close to the second air outlet 311a.

[0030] In the exemplary embodiment provided by the present disclosure, the air duct 4 can be arranged on the air outlet section 311 in any suitable manner, and the present disclosure does not limit this. Figure 1 , Figure 3 as well as Figure 4 As shown in the figure, a connecting port 311b is provided on the air outlet section 311, and the air duct 4 is connected with the air outlet section 311 through the connecting port 311b. The air outlet section 311 has a first side and a second side arranged opposite to each other in the longitudinal direction. The air outlet section 311 and the main body 312 form a volute tongue 313 on the first side, and the connecting port 311b is arranged close to the second side. Here, for the centrifugal fan 3, since the wind speed near the second side in the air outlet section 311 is greater than the wind speed near the first side, therefore, by arranging the connecting port 311b on the second side, it can be ensured that the air outlet section 311 forms a large negative pressure at the connecting port 311b, which is conducive to the smooth introduction of natural wind in the room.

[0031] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 , Figure 3 as well as Figure 4 As shown in , the second air outlet 311a has a midpoint a in the longitudinal direction, and the midpoint a coincides with the median plane b, wherein the median plane b extends vertically and is arranged parallel to the central axis c of the volute 31, and the air outlet section 311 is provided with a connecting port 311b in the portion between the second side and the median plane b. Here, for the centrifugal fan 3, in the air outlet section 311, since the area with a larger wind speed in the air outlet section 311 is mainly concentrated in the area between the median plane b and the second side, therefore, the connecting port 311b is provided in the portion between the second side of the air outlet section 311 and the median plane b, which can further ensure that the air outlet section 311 forms a larger negative pressure at the connecting port 311b, thereby further facilitating the smooth introduction of indoor wind.

[0032] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 and Figure 4As shown in the figure, a connecting port 311b can be provided on the air outlet section 311, and the air duct 4 is connected to the air outlet section 311 through the connecting port 311b. The vertical indoor unit can also include an opening and closing structure, and the opening and closing structure is used to selectively open the connecting port 311b. Through such a setting, the temperature of the air blown out by the vertical indoor unit can be flexibly adjusted as needed, that is, the vertical indoor unit of the present disclosure can have a first working mode and a second working mode. In the first working mode, the opening and closing structure can close the connecting port 311b, and in the second working mode, the opening and closing structure can close the connecting port 311b. The air inlet 12 stops taking in air, while the first air inlet 11 continues to take in air normally, thereby quickly lowering or raising the indoor temperature; in the second working mode, the opening and closing structure can open the connecting port 311b, at which time the second air inlet 12 takes in air, while the first air inlet 11 continues to take in air normally, and these two parts of air are mixed in the volute 31 of the fan 3 and then blown out through the first air outlet 13. In this way, the temperature of the air blown out through the first air outlet 13 can be avoided from being too low or too high compared to the initially set temperature, thereby improving the user's comfort.

[0033] In the exemplary embodiments provided in the present disclosure, the opening and closing structure can be set to any suitable structure, and the present disclosure is not limited to this. Figure 1 and Figure 4 As shown in , the opening and closing structure may include a valve plate 5, which may be arranged at the communication port 311b in a movable manner, so that the selective opening and closing of the communication port 311b can be achieved by the translation of the valve plate 5, and the structure is simple and easy to achieve. Here, according to some embodiments, the opening and closing structure may include a motor and a transmission structure, and the transmission structure may be constructed as a gear rack structure, so that the motor drives the valve plate 5 to move through the gear rack structure, thereby achieving the selective opening and closing of the communication port 311b. Of course, in other embodiments, the valve plate 5 may also be arranged at the communication port 311b in a rotating manner, thereby achieving the selective opening and closing of the communication port 311b. Here, according to some embodiments, the valve plate 5 may be hinged at the communication port 311b. At the same time, the opening and closing structure may also include a telescopic cylinder, and the output end of the telescopic cylinder is connected to the valve plate 5, so that the valve plate 5 can be opened or closed under the drive of the telescopic cylinder.

[0034] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 1 to 4 As shown in , in order to make the wind speed of the vertical indoor unit lower and softer, the area of ​​the first air outlet 13 can be set to be larger than the area of ​​the second air outlet 311a. Here, in order to facilitate the connection between the volute 31 of the fan 3 and the first air outlet 13, the vertical indoor unit can be set to further include an air duct body 6, and the second air outlet 311a of the volute 31 is connected to the first air outlet 13 through the air duct body 6.

[0035] In the exemplary embodiment provided by the present disclosure, the first air outlet 13 and the second air inlet 12 can be respectively arranged on opposite sides of the housing 1, so that on the one hand, the mutual interference between the air inlet and the air outlet of the vertical indoor unit can be avoided, and on the other hand, the aesthetics of the vertical indoor unit can be improved. Figure 1 As shown in , when the first air outlet 13 is arranged at the front side of the housing 1 in the lateral direction, the second air inlet 12 can be arranged at the rear side of the housing 1 in the lateral direction.

[0036] In the exemplary embodiment provided by the present disclosure, in order to improve the aesthetics of the vertical indoor unit and thus further improve the user experience, the first air inlet 11 and the second air inlet 12 can be arranged on the same side. Figure 1 As shown in FIG, when the first air inlet 11 is disposed at the rear side of the housing 1 in the lateral direction, the second air inlet 12 may also be disposed at the rear side of the housing 1 in the lateral direction.

[0037] When the vertical indoor unit of the present disclosure is used, Figures 1 to 4 As shown in, a first air inlet 11, a second air inlet 12 and a first air outlet 13 can be arranged on the shell body 1 along the horizontal direction, and the first air inlet 11 and the second air inlet 12 are arranged on the rear side of the shell body 1, that is, the side away from the user, and the first air outlet 13 is arranged on the front side of the shell body 1, that is, the side facing the user. A heat exchanger 2, a volute 31, an air induced duct 4 and an air duct main body 6 are arranged in the shell body 1, wherein the heat exchanger 2 is arranged at the first air inlet 11 in the shell body 1, the volute 31 has a second air outlet 311a with an opening facing upward and a central axis c arranged along the horizontal direction, the second air outlet 311a is connected with the first air outlet 13 through the air duct main body 6, the volute 31 includes a main body 312 and an air outlet section 311, and along the longitudinal direction, a connecting port 311b is opened on the side of the air outlet section 311 away from the volute tongue 313, and the second air inlet 12 is connected with the connecting port 311b through the air induced duct 4. Here, in order to enable the vertical indoor unit to switch between different working modes, a valve that can be opened and closed can also be provided at the communication port 311b. In this way, when indoor temperature adjustment is required, it can be achieved through the following two working modes:

[0038] In the first working mode, the first air inlet 11 is opened and the second air inlet 12 is closed. At this time, the wind from the first air inlet 11 flows into the volute 31 after passing through the heat exchanger 2. Afterwards, under the action of the fan 3, the wind passes through the main body 312, the air outlet section 311 and the air duct body 6 in sequence and blows out from the first air outlet 13. The temperature of the wind blown out in this mode is different from the set temperature to a certain extent, so the comfort level is poor.

[0039] In the second working mode, the first air inlet 11 and the second air inlet 12 are opened at the same time. At this time, the wind entering the volute 31 includes two parts, one part comes from the first air inlet 11, and this part of the wind flows into the volute 31 after heat exchange, and the other part of the wind comes from the second air inlet 12, and this part of the wind does not pass through the heat exchanger 2, but flows directly into the volute 31 through the induced air duct 4. Afterwards, the wind from the second air inlet 12 and the wind from the first air inlet 11 are mixed in the volute 31 and the temperature of the wind from the first air inlet 11 is adjusted. Afterwards, it is blown into the room through the air duct main body 6 and the first air outlet 13. The temperature of the wind blown out in this mode is close to the set temperature, so it is more comfortable and pleasant.

[0040] In the above process, the switching between the first working mode and the second working module is achieved by controlling the opening and closing of the valve plate 5 arranged at the connecting port 311b. For example, when the valve plate 5 is movably arranged at the connecting port 311b through a motor and a gear rack structure, the motor is controlled to drive the valve plate 5 to switch between the position of opening the connecting port 311b and the position of closing the connecting port 311b through the gear rack transmission mechanism.
